SULKY-PLOW.

SPECIFICATION forming part of Letters Patent No. 257,603, dated May 9, 1882..

Application filed March 9, 1882. (No model.)

To all whom it may concern:

Be it known that I, JACOB Nicnwoon, of Warsaw, in the county of Kosciusko and'State of Indiana, have invented certain new and useful Improvements in Sulky-Plows; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

Figure 1 is a perspective view. Fig. 2 is a horizontal sectional view, and Fig. 3 is a vertical sectional view taken through the operating-lever.

Corresponding parts in the several figures are denoted by like letters of reference.

This invention relates to sulky-plows; and it consists in certain improvements in the mechanism for adjusting the furrow-wheel or I raising or lowering it, so as to cause the plow to run at an even depth in hilly or undulating land, as will be hereinafter more fully de' scribed, and particularly pointed out in the claim.

In thedrawings hereto annexed, A represents the axle, which isprovided at one end with aspindle for the wheel B. Near the other end of axle A. is pivoted a stub-axle, 0, adapted to swingin a vertical plane, and having at its outer end a spindle for the furrow-wheel D. The stub-axle G is provided upon its front side, and near its inner end, which is flattened or widened, as at E, with a series of cogs or teeth, F.

G is a bracket firmly secured to the front side of axle A, and having a recess, H, to receive the extreme inner end of the stub-axle, which is thus held firmly braced against any tendency to swing horizontally. Bracket G has a segmental series of teeth, I, and pivoted to the side of said bracket is alever, J, having a spring-catch,K, engaging said teeth, so that said lever shall be held atany position to which it may be adjusted. The head of lever J is segmental in shape,and is provided with teeth L, engaging the teeth F upon the end of the stub-axle O, which may thereby be turned upon its pivot, thus raising or lowering the furr0w-wheel, as may be required.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States- The combination of the axle A, the pivoted stub-axle 0, provided near its inner end, which is flattened at E, with teeth or cogs F, the bracket G, having recess H and segmental series of teeth I, and the lever J, having segmental head provided with teeth L, and springcatch K, all arranged and operating substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto 'a-ffixed my signature in presence of two witnesses.
